If I copy my wallet.dat file from my win7 laptop at work, can I copy it onto my Ubuntu Linux computer at home? If I do, will sending bitcoin from the laptop be reflected automatically on the linux box? Or will I have broken something and end up loosing BitCoin?  Thanks (I do not want to use a wallet in the cloud for this)

you're fine for viewing balances, but as soon as you spend from one wallet, they'll become unsynchronised.

i'm actually investigating the use of truecrypt+dropbox for a similar purpose.

you're fine for viewing balances, but as soon as you spend from one wallet, they'll become unsynchronised.

To elaborate, the wallet from which you spend the coins will generate a hidden "change" address which will not be present on the other wallet*, causing you to lose a few coins (actually, you don't really lose them, they'll just only be visible (and spendable) from one wallet and not the other). However, if you always create a new copy of your wallet file after any time you spend some coins or create a new address, and remember to always transfer this up-to-date wallet file before you do anything else, there'll be no problem.

*Actually, I think the standard client generates a certain number of change addresses in advance for the sole purpose of avoiding this exact problem, but I'm not 100% sure. Best to play it safe and keep your wallet files synchronised.

Put your wallet on USB falsh disk and make symlink in .bitcoin/ directory
I am using modified launcher in ubuntu which unmount my USB after I close the client and tell me (via notify-send) when it's safe to remove it from PC.

Thanks for the answers.  I was hoping Bitcoin Armory would be able to do this, but it wont start on my win7 laptop.  What if I make a symlink to wallet.dat and put it in the UbuntuOne area of both of my computers?  Think that will work?
